 In the 80s and 90s, most video game screens had a 4:3 aspect ratio. Nowadays, screens mostly use a 16:9 ratio, which means that they provide extra space on the sides compared to a 4:3 aspect ratio.
-Rather than stretching out the 4/3 image to fit into a 16/9 model, you can fill the extra space with a background image that provides an even more immersive experience. You can simulate the looks of an old TV set, or even a background that matches the game you are playing. We call this type of decoration a //bezel//.

-If you have a nice TV and ask for a 4K 3840x2160 resolution to the emulators, but with a bezel that is HD 1920x1080: by default Batocera will add black borders around the bezel. If you want your display to be full screen, you can either:
+===== 4K TV or Ultra Wide Monitors =====
-  - switch to a lower resolution (like 1920x1080)
+If you have a nice TV with a 4K resolution 3840x2160, or if you use an ultra-wide monitor, or if you basically use emulators with a resolution that is above 1920x1080 (larger, or taller), you might have distorted bezels, The reason is that Batocera ships default bezels with a HD 1920x1080 resolution. To fix that, several options, you can either:
-  - turn on the **STRETCH BEZELS** option in **GAMES SETTINGS**
-  - add a line ''mame.bezel_stretch=1'' in your ''batocera.conf'' for each emulator you want to stretch, or ''global.bezel_stretch=1'' if you want to enable it for all systems.
+  - switch to a lower resolution (like 1920x1080) - which might not look good for non 16:9 monitors and TV.
+  - or turn on the **STRETCH BEZELS** option in the **GAMES SETTINGS** -> **DECORATIONS** menu.
+  - or add a line ''mame.bezel_stretch=1'' in your ''batocera.conf'' for each emulator you want to stretch, or ''global.bezel_stretch=1'' if you want to enable it for all systems.

 Turning on bezel stretching for high resolutions has a significant impact on emulation performance.

+===== 720p TVs =====
+If you have a TV with 720p resolution, you might also have issues with distorted bezels. You can attempt to resolve this by making the following two changes in the Batocera menu:

 A bezel is composed of 2 files. A ''.png'' file and a ''.info'' file. See explanations below.
+<WRAP center round tip>
+TVsIan has created a script which can automatically calculate the required ''.info'' files based on the transparent parts of the bezel's ''.png'' file. [[https://github.com/TVsIan/bezeltools|Read its usage instructions here.]]

 Bezels for a specific game on a specific system must be placed in the ''games/<system>/'' directory and have the same name as the ROM.

+===== Custom tattoo image (additional overlays) =====
+Batocera **v33** and higher now support being able to use a custom image overlaid on top of your decoration:
+{{:tattoo_on_decoration.png?720|A classy logo displayed in the top left.}} {{:system_controls_overlay.png?720}}
+This can be useful for two applications:
+  * remember what is the button mapping for the system you are playing (where on Earth are those Megadrive/Genesis ''A''/''B''/''C''/''X''/''Y''/''Z'' buttons on my controller??)
+  * streamers putting their metadata/chat decorations on the side or for displaying helpful controller overlays for systems you may not be as familiar with (useful for games that feature on-screen button prompts).
+To set the tattoo globally, press ''[START]'' and navigate to **GAME SETTINGS** -> **DECORATIONS** -> **SHOW TATTOO OVER BEZEL** and set it to whichever option is preferred. To set a tattoo for a particular system, go to that system's gamelist, press ''[SELECT]'' and navigate to **ADVANCED SYSTEM SETTINGS** -> **DECORATIONS** -> **SHOW TATTOO OVER BEZEL**. If the **DECORATIONS** menu is not present then decorations, and by extension tattoos, cannot be used on that system yet.
+This can also be configured manually in ''batocera.conf'':
+<code>
+# Enable tattoos for all systems: you can choose between 'system' (controller mappings per system), 'custom' (add your own PNG) or '0' to disable.
+global.bezel.tattoo=system
+# Display the tattoo in the upper left corner (can be either NW, NE, SW or SE):
+global.bezel.tattoo_corner=NW
+# PNG (transparent backgrounds work best) location:
+global.bezel.tattoo_file=/userdata/system/my_logo.png
+# Specify a different tattoo for a specific system (overriding the default):
+gbc.bezel.tattoo_file=/userdata/system/batocera-logo-transparent.png
+# Disable the tattoo for a specific system (overriding the default):
+snes.bezel.tattoo=0
+</code>
+The corner selection can be different for each system: look at the example below with ''NW'' for GB and ''SW'' for FBNeo, each of them with their ''system'' tattoo selection:
+{{:tattoo_system_corners.png?nolink&600|NW and SW corners}}

+===== Troubleshooting =====
+==== There's a large number of systems missing from the downloadable Bezel Project bezels in the content downloader ====
+It is possible that this may happen if you have a special custom command for mounting the ROMs folder, such as:
+<code>
+sharenetwork_cmd1=mount.cifs -o username=mylogin,password=mymdp //servername/share3/roms /userdata/Server_Roms
+</code>
+this could interfere with the system list being properly loaded in the content downloader. To workaround this, temporarily use internal storage, download the bezels, and re-setup the custom NAS commands.
+Using the regular ''ROMS@IP-ADDRESS...'' syntax also works.
